On the applicability of `quantile_function` and `nx.searchsorted` on tensors wider than 2D

3

## Describe the bug Pre-story to this question is the following operation within `quantile_function` helper for 1d solvers: [link](https://github.com/PythonOT/POT/blob/829ce41b85dd1d42da84035fc06296650fae1968/ot/lp/solver_1d.py#L41-L42). Transpose is only well-defined for 2D PyTorch tensors: for 1D it...
